function of a throttle body
#1

Well I don't think that it would be worth the time to make a new TB yourself. I'm not doubting your ability but it would not be so easy IMO. The aftermarket TB's work if your engine can use the air that a larger hole can give you. I'm new to the I6 but most people have said a stock engine it's a waist of money.
Hope that helps

Well this is how it works It controls the amount of air allowed to come in to the engine. If you removed the TB and started the engine the motor would rev out of control.
FYI
The TB is closed when you have you foot off the gas, the idle control is done with a small valve on the intake called the air idle control valve.
Also
This is why there is no difference, if your air flow threw the head is max-ed out with the stock TB for sake of argument, then increasing TB size could not change the flow volume of air threw the head which was already max-ed out. If you ported the head to increase the max air volume flow then a after market TB could make more power.
Hope that helps.
